Failure Inferencing-based Fast Re-routing (FIFR)
Description
-
With the emergence of Voice over IP and other real-time business
applications, there is a growing demand for an IP network with high
service availability. Unfortunately, in today's Internet, transient
failures occur frequently due to faulty interfaces, router crashes,
etc., and current IP networks lack the resiliency needed to provide
high availability. To improve failure resiliency without jeopardizing
routing stability, we propose failure
inferencing based fast rerouting (FIFR) approach that exploits the
existence of a forwarding table per line-card, for lookup efficiency
in current routers, to provide fast rerouting similar to MPLS, while
adhering to the destination-based forwarding paradigm.
